Penumatic tire tread and buttress



FIG. 1 is a perspective view, partly schematic, of a pneumatic tire tread and buttress embodying my new design, it being understood that the pattern is repeated throughout the circumference of the tread and buttress, as shown schematically by solid lines, and that the buttress pattern is repeated on the opposite side; and,

FIG. 2 is an enlarged, fragmentary development plan view of the tread and buttress of FIG. 1.

The broken line showing of environmental structure in FIG. 1 of the drawing is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a pneumatic tire tread and buttress, as shown and described.
